I finally played BOTW and Rune factory Guardians of Azuma and it was really inspiring.

So then I implemented a new skybox, weather system, integration with TVE to make plants white during snow, an UBER shader for gameobjects to make snow appear on houses, a terrain shader to make the terrain snowy. Then did the same exercise for rain. Then I made the playable character react to rain. Then I attached some rain drop effect on the character to play when it stops raining, to show he is wet.

Then I realized that I got sidetracked and that I totally neglected the game part of the game.
